You are certainly free to continue to believe that time
happens twice, but I tell you that this way lies madness,
or at least a good headache. I really believe that the
path of least resistance is to accept that time only
happens once.

Sarah:
I agree.  Life is simpler if one stops worrying about multiple
alternate layered realities and learns to love the Bill and Ted school
of time travel.  Bill and Ted visited themselves in the Circle K
parking lot, which only happened once, because there is only one
reality.  Just like Harry visited himself to drive off the Dementors.
If there had been a first reality where that didn't happen, then Harry
would surely have experienced it.  But he didn't.  He experienced that
three hours two times, and the same events happened the same way both
times, even if he interpreted them differently.

And by that token:

What if Harry goes back in time and destroys the Hocruxes before
his family is attacked? Harry would change the course of history.
Not only will LV die completely that night, he would save the
lives of Dumbledore, Sirius, Cedric, and many others.

Sarah:
It's been well established in interviews that one thing magic can't do
is bring back the dead.  (Except as Inferi, which isn't quite the
same.  :) )  The Time-Turner is magic, therefore it can't bring back
the dead.  This is why the belief in a "first reality" scenario where
Buckbeak actually died breaks our understanding of the Potterverse,
and opens up possibilities like this where every dead person ever
isn't beyond hope of being brought back.

If Harry is ever going to do something like this, his future self
would have already done it in his past.  He would have grown up with
parents.  Since he didn't, an attempt to do so would either fail (most
likely) or I don't know, explode the universe or something (less
likely).

I hope this is making sense.
